Gaggia Classic
The most modified and most repaired home espresso machine in the world. Parts are cheap, the layout is simple, and the community has documented every screw.
Which version do you have?
Three generations with different boilers and valves. Check the plate on the underside.
| Version | Years | How to recognise it |
|---|---|---|
| Classic (original) | 1991–2014 | Made in Milan; aluminium boiler, 3-way solenoid, rocker switches |
| Classic 2015 | 2015–2018 | Philips-era redesign, no solenoid on some units, different boiler; parts differ |
| Classic Pro / Evo Pro / E24 | 2019–today | Return to the original layout, new steam wand, 9-bar OPV spring on Evo |
Typical faults
- Shots pour too fast or too slow. Often the OPV spring (15 bar from factory); a 9-bar spring is the standard fix.
- Water drips from the group when idle. Group gasket or solenoid valve.
- No steam, or weak steam. Steam thermostat (145 °C) or scale.
